对称性对原子团簇Ar_3低激发能谱的影响

Effect of Symmetry in the Low-lying Energy Spectrum of Ar 3

采用少体物理方法，计算了惰性元素三原子团簇Ａｒ３的低激发能谱，分析了量子力学对称性对Ａｒ３的几何结构和内部运动的影响，给出了Ａｒ３低激发能谱的几条转动带。

The few-body theory is applied to the calculation of the low-lying energy spectrum of the Ar 3 bound by pairwise Lennard-Jones potential.We analyse the effect of the quantum mechanical symmetry on the structures and internal motions of a Ar 3 cluster.Some rotor bands of the low-lying states of a Ar 3 cluster are given.
